DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be provided in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

With referring to FIG. 1, a block diagram and a perspective view of the present invention are illustrated. The present invention includes the following elements.

A power source 100 serves for generating power. The power source 100 is connected to a first transmission system 200 and a second transmission system 300.

A waste liquid collecting tray 40 is connected to the first transmission system 100 for collecting waste liquid. The waste liquid in the waste liquid collecting tray 40 can flow out from the liquid draining tube 41. Preferably, a filter net 42 is installed at a front end of the liquid draining tube 41 for filtering impurities from the waste liquid.

A brush roller 30 is connected to the waste liquid collecting tray 40. The rotary shaft 31 is driven by the first transmission system 200 to rotate. The brush roller 30 has a plurality of hairs around the lateral side of the roller 30. The hairs of the brush roller 30 serve to brush a chain of a bicycle. A liquid draining tube 41 is installed at a lower side of the brush roller 30.

A cleaning liquid reservoir 70 is filled with cleaning liquid. A pump 60 is connected to the second transmission system 300 and is driven by the second transmission system 300. The pump 60 serves to pump cleaning liquid out of the cleaning liquid reservoir 70. A lateral side of the cleaning liquid reservoir 70 has an opening 72. The liquid draining tube 41 is connected to the opening 72. An upper end of the cleaning liquid reservoir 70 is extended with a nozzle 74. When the pump 60 acts, the cleaning liquid will be driven to flow to the nozzle 74. The nozzle 74 faces the hairs of the brush roller 30 so as to spray cleaning liquid toward the hairs. The cleaning liquid will be absorbed by the hairs.

With referring to FIGS. 2, 3 and 4, a detailed structure of those systems illustrated in FIG. 1 is illustrated.

The brush roller 30 is a roller extended with a rotary shaft 31. The rotary shaft 31 is driven by the first transmission system 200 to rotate. The brush roller 30 has plurality of hairs 34 around the lateral side of the roller 30. Referring to FIG. 3, the hair 34 assembly has a U shape cross section.

The waste liquid collecting tray 40 is installed below the brush roller 30 for receiving falling waste liquid from the brush roller 30.

A cleaning unit 80, for example, a sponge or a cloth, is installed beside the brush roller 30. The cleaning unit 80 serves to hold the dripping of the waste liquid and to further clean the chain brushed by the hairs of the brush roller 30.

The power source is a motor 10. A power wire 4 is connected to an external power source and a battery 20 for supplying power to the motor 10.

The first transmission system 200 includes a first pulley 12. An axial center of the first pulley 12 is connected to the spindle 11 of the motor 100. A rotary shaft 31 has one end extended from an axial center of the brush roller 30. Another end of the axial shaft 31 is connected to a roller pulley 32. A flexible extension shaft 33 winds around the first pulley 12 and the roller pulley 32. Thus as the motor 10 runs, the spindle 11 will rotate so as to drive the first pulley 12, the soft wire 33 and the roller pulley 32 to rotate. As a result the brush roller 30 rotates.

The second transmission system 300 has the following elements.

A second pulley 13 is axially connected to the spindle 11 of the motor 10. A second flexible extension shaft 51 winds through the second pulley 13 and then wind through a rotary wheel 50. A first linkage 52 connected to a surface of the rotary wheel 50 at an eccentric position. The first linkage 52 is connected to a second linkage 53 by using a shaft 54. The second linkage 53 axially moves along the shaft 54 and the first linkage 52 also axially moves along the shaft 54.

The pump 60 is an air pump 60 which is driven by the second linkage 53.

A check valve 73 is installed in the opening 72 so that liquid only flows from the liquid draining tube 41 to the cleaning liquid reservoir 70, but can not flow from the cleaning liquid reservoir 70 to the liquid draining tube 41.

With reference to FIG. 5, it is illustrated that in the present invention, a box 90 can be used to install the motor 10, the first pulley 12, the second pulley 13, the rotary wheel 50, the first linkage 52, and the second linkage 53, etc. A buckle 76 serves to lock and unlock the upper cover of the cleaning liquid reservoir. When the upper cover is unlocked, liquid can be drained out or added thereto. When the upper cover is locked, the cleaner can be operated.

Referring to FIG. 6, the second embodiment of the present invention is illustrated. This embodiment is similar to above mentioned embodiment, and thus in the following, only those differences therebetween are described.

In FIG. 6, it is illustrated that that power source 100 is formed by two motors 101 and 102. The motor 101 serves to drive the brush roller 30 and the motor 102 serves to drive the rotary wheel 50. The first transmission system 200 is the spindle 12 of the spindle 11 of the motor 101. The second transmission system 300 includes a rotary wheel 50, a first linkage 52 and a second linkage 53. The first linkage 52 connected to a surface of the rotary wheel 50 at an eccentric position. The first linkage 52 is connected to the second linkage 53 by using a shaft 54. The second linkage 53 axially moves along the shaft 54 and the first linkage 52 also axially moves along the shaft 54.

Other power source, such as engines, can be used to replace the motor in above embodiments, however motors are preferable in application.

Operations of the present invention will be described herein.

In operation, a bicycle chain (or free wheel or chain wheel, in the following, the chain is used as an example for description). The chain is placed upon the hair 34 of the brush roller 30. Then the power of the motor is actuated. The air pump 60 is actuated by the motor 10 through the second transmission system 300 so that cleaning liquid will spray to the hair 34. Furthermore, the first transmission system is actuated by the motor 10 so as to actuate the brush roller 30 to rotate and the chain is cleaned by the clean liquid in the hair 34 of the brush roller 30. Thus the chain is cleaned. Moreover, the waste liquid from the hair 34 is collected by the waste liquid collecting tray 40 and then is filtered by the filter net 42 and then returns to the cleaning liquid reservoir 70 through the liquid draining tube 41 so as to form a cleaning cycle. Another, the cleaning unit 80 will wipe the chain for removing the dirt and grease on the chain.

Advantages of the present invention are that the present invention can be used to clean chains, free wheels and chain wheels of bicycle automatically and easily.
